[MPTCP] [PATCH mptcp 0/4] four small cleanups and fixes

[Florian Westphal]

[-- Attachment #1: Type: text/plain, Size: 1195 bytes --]

1. cleanup: mptcp_subflow_get_map_offset arg can be const.
2. fix: don't advance snd_una past the write sequence.
3. cleanup: use existing helper rather than open-coding it
4. fix: avoid blocking kworker forever when polling mptcp socket.

All paches can be squashed, I've added squashto hints.
